Grinding Disc KLINGSPOR 45027A for Steel, 125×6×22 mm, Abrasive A24R/36

KLINGSPOR grinding disc 45027A is a convex abrasive wheel designed for working on steel. With dimensions 125×6×22 mm and abrasive grade A24R/36, the disc is intended for use with angle grinders to remove material, prepare surfaces and refine edges on steel components. The shape and grain selection provide controlled stock removal while maintaining disc stability during common metalworking tasks such as removing weld spatter, deburring edges and shaping small sections of metal.

Advantages

The abrasive composition and medium-coarse grit offer a balance between cutting speed and surface finish, enabling efficient material removal without excessive loading. The convex profile improves access to narrow joints and curved surfaces. The disc is compatible with standard 125 mm angle grinders and is suitable for continuous grinding operations on steel when used with appropriate speed and clamping.

Suitable for

• Deburring and edge rounding of steel parts
• Grinding and smoothing weld seams
• Removing rust, scale and surface contaminants from metal
• Shaping and profiling small metal components in fabrication and repair

Key specifications

• Disc diameter: 125 mm
• Thickness: 6 mm
• Arbor hole: 22 mm
• Abrasive type and grit: A24R/36 (aluminium oxide, medium-coarse)
• Convex wheel profile for access to joints and contours

How to use

Mount the KLINGSPOR 45027A grinding disc on a compatible 125 mm angle grinder with a matching 22 mm arbor fit and secure the disc with the correct flange and nut. Before use, inspect the disc for damage and do not use if cracked or chipped. Operate the grinder at the recommended speed for the disc and let the abrasive do the cutting—apply steady, moderate pressure and avoid forcing the disc into the workpiece. Use controlled strokes along the welds or edges to achieve uniform material removal and avoid overheating the metal. Replace the disc when grinding performance diminishes or if any damage is detected.

Usage recommendations

Use appropriate personal protective equipment including safety goggles, face shield, hearing protection, gloves and respiratory protection when grinding steel. Ensure the angle grinder’s guard is fitted and work in a well-ventilated area. Select an angle and pressure that maintain disc stability; for heavy stock removal consider multiple light passes rather than high pressure to extend disc life.
